Thaum tshawb nrhiav ntau hom log urethane, peb yuav tsum hais txog lawv cov yam ntxwv tshwj xeeb thiab cov xwm txheej ntawm daim ntawv thov. Polyurethane ua cov khoom siv ua tau zoo. Nrog nws cov khoom siv lub cev thiab tshuaj zoo heev. Nws nyob hauv txoj haujlwm tseem ceeb hauv kev tsim khoom log.
Ua ntej. Cia peb saib cov log polyurethane (TPU). Cov log no muaj lub hauv paus polypropylene lossis nylon. Los ntawm kev txhaj tshuaj molding thib ob, lub log polyurethane nto yog tsim rau ntawm ntug sab nraud ntawm lub hauv paus. Cov log TPU tsis yog tsuas yog muaj cov yam ntxwv ntawm kev tiv thaiv hauv pem teb, nqus cov kev co, tsis muaj cim thiab tsis muaj xim. Nws kuj muaj kev tiv thaiv zoo rau kev sib txhuam thiab xeb. Muaj peev xwm dov tau yooj yim ntawm ntau qhov chaw. Tsis tas li ntawd. Nws cov xim tuaj yeem hloov kho raws li qhov xav tau. Hloov kho rau cov kev xav tau ntawm ntau lub sijhawm. Txawm li cas los xij. Nws tsim nyog sau tseg tias Hauv qhov chaw kub. Lub peev xwm thauj khoom ntawm lub log TPU yuav raug txo qis.
Kauj ruam tom ntej yog nchuav lub log polyurethane (CPU) elastomer. Cov log no muaj lub plawv hlau lossis txhuas ua lub plawv. thermosetting polyurethane elastomers pwm los ntawm kev tshuaj lom neeg. Tsim ib lub log nto tom qab kho ntawm qhov kub siab. CPU log muaj tib qhov zoo ntawm kev tiv thaiv hauv pem teb, tsis muaj cim thiab tsis muaj xim. Nws kuj tseem tiv taus UV thiab tsis sib txhuam, ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau qib siab ntawm kev ua haujlwm xis nyob. Txawm li cas los xij. Nws tsis tiv taus dej kub, dej pa, thiab lwm yam ... Yog li ntawd yuav tsum ceev faj thaum siv nws hauv qhov chaw tshwj xeeb.
Cia peb tham txog lwm lub log polyurethane (CPU) uas raug tsim los. Cov log no kuj yog ua los ntawm cov thermoset polyurethane elastomers uas raug tshuaj lom neeg ua rau muaj kev sib xyaw ua ke. Muaj cov txiaj ntsig zoo ib yam li cov log CPU uas tau piav qhia saum toj no, piv txwv li tiv thaiv hauv pem teb, tiv taus kev sib txhuam, thiab lwm yam. Qhov tshwj xeeb tshaj yog qhov tseem ceeb. Nws muaj qib qis heev ntawm kev hloov pauv mus tas li, qhov tsis kam dov qis. Muaj peev xwm tiv taus cov khoom thauj dynamic ntawm qhov ceev ceev. Zoo tagnrho rau kev siv hauv qhov xwm txheej ceev ceev.
Thaum kawg. Cia peb saib lub log polyurethane (PUE) ua npuas ncauj. Nrog nws cov qauv microporous tshwj xeeb, lub log no Qhia txog cov yam ntxwv xws li qhov ceev tsawg, lub teeb yuag thiab yooj yim deformation. Nws kuj muaj ntau yam khoom zoo heev xws li kev thauj khoom siab, elasticity siab thiab folding tsis kam. Cov yam ntxwv ntawm PUE log no ua rau lawv yog qhov kev xaiv zoo tshaj plaws ntawm cov khoom siv rau casters. Txawm hais tias nws yog lub suab thiab lub zog nqus lossis kev co damping thiab cushioning. Tag nrho ntawm lawv tuaj yeem qhia lawv cov txiaj ntsig tshwj xeeb.
Zuag qhia tag nrho. Cov log tsheb Polyurethane, nrog lawv cov kev ua tau zoo tshaj plaws thiab ntau hom Nws yog siv dav hauv ntau qhov chaw. Los ntawm TPU log uas tiv thaiv hauv av thiab nqus kev poob siab. mus rau UV thiab kev sib txhuam ntawm CPU log. Ntxiv rau qhov ceev qis thiab lub teeb ntawm PUE log. Txhua hom polyurethane log ua lub luag haujlwm tseem ceeb hauv nws thaj chaw. Xaiv lub log urethane zoo rau koj cov kev xav tau. Tsis yog nws tsuas yog ua kom muaj kev ua haujlwm zoo dua. Nws kuj tseem muab kev paub zoo dua thiab muaj kev nyab xeeb.
